Research of manufacturing enterprise information system integration based on extended ESB

摘要

Information systems bring out "Information Island" problem to manufacturing industry while promoting its informationization level. How to integrate these systems effectively is widely concerned and researched. In this paper, researches on information system integration by domestic and foreign scholars are summarized. An extended ESB (E-ESB) based information system integration model is proposed. It has 4 layers including presentation layer, bus layer, service layer and data layer. Information model of the architecture is proposed to describe how the messages interact within all parts. At last, key technologies in integration such as centralized authorization management, metadata adaptation, reconfigurable services and multi service operating mechanism are discussed.
